Answer
$(5,0)$
Work Step by Step
Use the fact that a point $r$ units from the origin with an angle $\theta$ from the horizontal is located at $(r\cos\theta,r\sin\theta)$. Using $r=5$ and $\theta=0^\circ$, the point is located at $$(5\cos(0^\circ),5\sin(0^\circ))=(5,0)$$ Verify these trigonometric values using the unit circle if necessary.
